Abstract

<PICT:1100072/C6-C7/1> Ingots of aluminium or its alloys are heattreated in a direct fired furnace in contact with combustion product gases after first pre-heating them out of contact with these gases until at least their surface temperature is above the dew point of water vapour (between 130 and 150 DEG F.) in these gases to prevent water staining and heavy surface oxidation. Fig.2 shows ingots 11 being charged into a circular furnace, loaded on to a circular endless conveyer 16, passing through first a preheat or warming zone 17 heated by induction or a radiant tube or initially warmed by direct firing from burners 18, then a direct fired zone 20 heated in contact with combustion product gases from burners 21 preferably natural gas fired, and a holding zone 22 with heating means 24, the zones being separated, preferably by air curtains 19, 23. Examples of known alloys which may be heated for hot-rolling at 850 DEG F. or homogenized by soaking at 950 or 1125 DEG F. are specified.
